Many factors are shown to influence an athlete´s performance such as good technical abilities, good mental skills and adequate body composition. In particular, good hydration status is critical during and after training sessions and competition events. As exercise performance and postexercise recovery can be significantly impaired when hydration status is not adequate, the aim of this study was to evaluate the impact of hydration status on recovery indexes on professional athletes. Twenty-eight professional soccer players, aged between 18 and 35 y, were subjects for the study. Body composition and in particular hydration status were assessed trough Bioelectrical Impedance Test (BIA) using single-frequency bioimpedance (BIA AKERN101). Recovery was analyzed using a specific test (GQR-TIA) where a scale from 0 to 10 indicates from "need absolute rest, no recovery" to "ready for the competition, total recovery". Statistical analysis was carried on using SPSSR. Correlation coefficients were calculated to assess the relationship between variables. Significance level was set at p.0.05.
